Turkish Physics Olympic Questions (The original question 13) I am waiting solutions since 2 months but they didnt publish. I can't sleep nights because I didnt solve problem 13 www. fen.bilkent.edu.tr...

ELevator slows down ward with a constant acceleration of 6 m/s2 or (a = 6 N/kg )

Lets suppose the elevator moves with constant velocity downward and a man press the button to stop elevator then elevator makes slowing down motion downward with a=6m/s2 and angle and height for the object changes with the time.

showthread.php?t=424269 BUT integral is difficult

solution how to? g'=16m/s2 is correct N-mg=ma+(m/r)Vfinal^2 Energy equation? m(g+a)Integral(rdr)? Because The height is changeabele for every second This is Turkish Physics Olympiad Question. I couldn't solve Or (1/2)mV^2 +m(g+a)Integral(rdr)= (1/2)mVfinal^2

Hello could you look at ? the post /showthread.php?t=612910 :)

any advice or solution? showthread.php?t=612910

any advice? showthread.php?t=612910

An elevator slows down with a 6 m/s2 acceleration and an object m=3 kg is freely released as shown in figure There is no friction between object an semispherical shape. The object reaches L point what is the force which the object exerts L point? A)120 N B)240 N C)360 N D)480 N E)600 N...
